Where else can you smack Andy Warhol in the face with a bat for a good cause, and then leave with a Little Debbie Ho-Ho?

The Brooklyn Museum celebrated its annual gala with a big twist — not only did the April 22 party feature a performance art piece, but the high-paying patrons were the performers.

Some of the clientele at the exhibition, called “American High Style: Fashioning a National Collection,” paid up to $1,500 for a chance to hack at the roasted pork that would be their dinner, dip crackers into artisanal, handcrafted cheese heads, and swing at a giant piñata depicting the head of Andy Warhol (which was filled with pastries).

“The after-party was insane,” said Mercedes Zuluaga, a museum supervisor.

Some hot celebs showed up, too. New York foodie mogul Jennifer Rubell set up the food-gone-art exhibition, in which each course was on a separate floor. Actress Chloë Sevigny went crazy for the giant mountain of potato chips. Fashion designer Zac Posen went for the wine. And uber-chef Mario Batali hung out by the meat table.

But the event wasn’t just a bunch of high rollers pigging out on eccentric dishes — it was held to preview the new fashion exhibition that will be open to the public on May 7. The proceeds — museum officials said they expect to have about $700,000, which makes sense considering a table reservation cost up to $50,000 — will go to the museum’s educational programs.
